First, an overview

 

According to the market demand, have highlighted the following characteristics design of man-machine FF60 small long endurance.

 

1) long endurance

 

2) large loading space

 

3) takeoff and landing ease of use

 

4) wide cruise speed range

 

Two, technical indicators

 

Maximum takeoff weight of 1) 60kg

 

2) maximum load capacity 15kg

 

3) cruise speed of 60 ~ 120km/h

 

4) life time 10h

 

5 wheeled emergency parachute landing).

 

Three, design characteristics

 

1, pneumatic layout

 

Double tail conventional layout, engine booster. The wing has a small angle, and the lateral stability of the aircraft in the super low altitude flight is promoted. The control surface is set to the rear wing (optimized single slotted flaps, do not participate in the flight control), aileron, elevator, Fang Xiangtuo.

 

Airfoil using wing and the rear wing two stage design, the rear wing can deflect, in the conventional single slotted flaps based on optimized slot parameters, and the main wing of repair type, can guarantee in wing deflection is larger range to maintain high lift to drag ratio.

 

Main geometric parameters:

 

Wingspan: 3.85M

 

Total length: 2.79M

 

Total height: 1.0m

 

Wing area: 1.50m2

 

Aspect ratio: 9.68

 

2, structural design

 

Main body is divided into an upper part, set up a bulkhead, respectively, the nose cabin (front landing gear, pitot tube, a counterweight, avionics), avionics and equipment cabin, the main oil tank, auxiliary fuel tank, an umbrella module. The tail box set the engine fairing, the space can accommodate generator.

 

The upper and lower body of the machine body is made of carbon fiber foam sandwich structure, and the aircraft electric and equipment cabin are provided with longitudinal reinforcing bars.

 

Where the wings join the fuselage without wing trim design, when the center of gravity change, easy to move a certain distance before and after the wing.

 

3, power plant

 

Engine: 120cc oil moving

 

Propeller: 26X12
